A Surface coverage Model for the Reaction of Ca(OH)2 with SO2 at Low Temperatures
描述二氧化硫與氫氧化鈣低溫反應的表面覆蓋模式
摘要
乾式和噴霧乾燥煙道氣除硫程序普遍使用氫氧化鈣作為吸收劑，氫氧化鈣與二氧化硫在這些程序的溫度下的反應可以用表面覆蓋模式很好地描述。此模式假設反應速率由發生在吸收劑吸附水分子的表面的化學反應所控制，且納入吸收劑表面被反應產物覆蓋的影響。本研究的結果有助於使用氫氧化鈣作為吸收劑的乾式與半乾式系統之設計與操作。

Hydrated lime (Ca(OH)2) is widely used as a sorbent in the dry and spray-drying flue gas desulfurization processes. The reaction of Ca(OH)2 with SO2 at low temperatures in these processes is well described by the equations obtained from a surface coverage model. The model assumes that the rate is controlled by the chemical reaction occurring on the water-adsorbed sorbent surface and considers the surface coverage by the product. The results of this study are useful for the design and operation of dry and spray-drying processes using hydrated lime.
